Appli ati nfiled February 12, 1903. Serial No. 143,091.

To aZZ whom it may concern:

Be it known that I, JOHN T. TRUITT, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Belt-Gearing for Extractors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improved driving-gear especially adapted for connecting the counter-shaft and the driven shaft of that class of laundrymachineryknown as an extractor, but also adapted for use in connection with other kinds of machinery; and it consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed outin the claim.

The object of my invention is to effect improvements in the driving-gear of this class whereby the slack in the flexible driving element or band may be taken up automatically, and thus adapt the driven shaft and countershaft to be run at any desired rate of speed and the speed thereof to be varied, as may be required under different conditions.

In the accompanying drawings, Figure 1 is a perspective view of an extractor provided with a driving gear embodying my improvements. Fig. 2 is a side elevation of one form of my improved driving-gear. Fig. 3 is a similar view at right angles to Fig. 2 looking in the direction of the arrow, the upper bearing and the bracket for supporting the two idle pulleys being omitted and the portion of the frame which is connected with the bracket being broken away. Fig. 4 is a side elevation of a modified form of my improved driving-gear.

In the form of my invention shown in Figs. 1, 2, and 3 the counter-shaft 1, which is at right angles to the driven shaft 2, is j ournaled in suitable bearings 3 and is provided with a fast drive-pulley 4 and a loose pulley 5 and is also provided with a pair of peripherallygrooved pulleys 6 7, the former being fast to the counter-shaft and the latter being loose thereon. The driven shaft 2 has a pulley 8.

An endless band 9, which is here shown as a rope, connects the pulleys 6, 7, and 8 and 1s provided with a take-up or compensating bight 10, which depends from the pulleys 6 7, its respective leads depending from opposite sides of said pulleys 6 7. This band engages the grooved peripheries of the respective pulleys, and their leads at points intermediate thereof are engaged by direction-pulleys 11, which have their bearings at 12 in a frame 16. The frame is secured to a suitable support, as a bracket 17, by means of a single bolt 18, which is located at a point between the planes of the two pulleys 11.

A yoke 19 is secured at its ends to the bolt or pivot on which the pulleys 11 are journaled and projects in front of the forward edges of the pulleys to strengthen the frame 16 and assist in preventing the band 9 from being thrown off the pulleys.

An idler-pulley 13 hangs in and is engaged by the bight of the driving-band and is here shown as provided with a weight 14, which depends therefrom. The function of this pulley and the take up or compensating bight of the endless driving-band is to take up the slack in the latter and enable the counter-shaft and driven shaft to be operated at any desired rate of speed and the speed thereof to be varied as may be required without causing the endless driving-band to slip on the driving or driven pulleys.

A belt may be substituted for the rope band within the scope of my invention, and I 1do not desire to limit myself in this particu- In the modified form of my invention (shown in Fig. 4) a single pulley 15 is employed on the counter-shaft in lieu of the pulleys 6 7 and is provided with a pair of peripheral grooves 15 15 for the driving-band, the groove 15 being of such size as to be closely engaged by the said band and the groove 15' being of suflioient width to enable the said band to slip thereon.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily apparent, it is thought, without requiring a more extended explanation.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A belt-gearing for extractors comprising a driving-shaft, a peripheral pulley therewith, a counter-shaft, a fast and a loose pulley thereon, said shaft being also provided with a fast and a loose grooved pulley, a support having a two-part frame provided with a single shaft having thereon a pair of pulleys separately mounted in eaohpart of the frame, a yoke pivoted to the ends of the single shaft and aring Weighted hanger, a driving-band mounted respectively on the pulley of the drivingshaft, the pulleys of the two-part frame, the depending pulley, and also on the grooved pulleys on the counter-shaft, substantially as specified.

In testimony whereof I have hereunto'set my hand in presence of tWo subscribing wit- 1o nesses.

JOHN T. TRUITT.
